Is there a way to point SW 2007 back to the original installation source when it can't find it. I have the 2007 DVD copied to my HD.I'm trying to update to SP3.1 from 3.0 and now the update can't locate the original installation source. I had no problems with any other SP until now.If I try browsing to the source file it's looking for, the file is where it was originally. If I try to point it to the DVD I get the same error message that the installation source can't be found. I could see if I've installed it from a different source but have always copied it to the HD and installed from there. No disk swapping that way.
